Description
Technical field
The present invention relates to the balance detection of fan propeller, especially a kind of detecting and correcting device of fan rotor dynamic balance.
Background technology
Along with the prosperity of electronics technology, fan extensively is employed.In the design of fan, the uneven distribution of leaf weight can cause the center of gravity of fan to overlap with its rotation center, make this fan when rotating because of the uneven bad shortcoming such as vibration that produces, and then make this fan propeller overload, reduce its fiduciary level and reduction of service life.Therefore in the quality control of fan, effectively balance detection is proofreaied and correct the generation that can lower the problems referred to above.The balance detection of rotating object generally is divided into " static equilibrium " and " transient equilibrium " two classes, and the rotor dynamic balancing that is applied to fan blade to proofread and correct be that most fan manufacturer are classified work necessary on the processing procedure as.For example, the blade behind the ejection formation (impeller) and load onto magnetic stripe after flabellum or rotor (rotor), all need carry out balance correction.
In the employed fan rotor dynamic balance measurement mechanism of prior art,, in order to this fan to be installed, and measure operation usually by independent measuring unit.One PC (Personal Computer) is connected in this measuring unit, in order to control this measurement operation and to carry out reception, storage and the computing of data.This measuring unit of aforementioned measurement mechanism often can't be good with this PC coupling, moreover because other measuring unit and this PC are provided, so this measurement mechanism occupies excessive volume, and and be not suitable for the manufacturing works of general fan.
Dynamic balance calibrating method generally is the dynamic balance calibration machine that has vibration transducer and a phasometer with, when rotating, measures by this fan the vibration signal of this fan, this vibration signal comprises the vibratory output of fan, such as the phase place of amplitude size (displacement), amplitude speed, amplitude acceleration, amount of unbalance and frequency etc., by phase effect Y-factor method Y or the uneven TRANSFER METHOD of standard component, measure the size and the position of the unbalance mass, of this fan propeller.Then, again with reference to a test stone, by lowering this unbalance mass,, or increase the mode of this unbalance mass,, to reach the requirement of test stone at its symmetric points.Yet prior art also fails to provide a kind of good standard in order to detect the quality of fan.
In addition, during the other feel that adopts that detects fan detects, axial (axial) vibratory output of fan propeller quite detects the vibration of being felt near staff, just can and replace feel detection step in order to simulation so detect axial vibration amount measured in the means for correcting at a fan rotor dynamic balance.Yet the device of commonly using only has the radial vibration inductor, that is whether the radial vibration amount that can only judge this fan propeller can't get rid of feel not good fan propeller by detecting.
Summary of the invention
In view of this, just there is the fan rotor dynamic balance that a kind of integral body need be provided to detect means for correcting, can meet under the common standard of accepting of industry member one, measure and calculate allowing of this fan propeller remaining uneven (Permissible Residual Unbalance) and angle correction, proofread and correct adjustment for the testing staff, and the axial vibration amount of this fan propeller of energy measurement, it is qualified to judge whether.
